John Legere is famous for being the sweariest man in the mobile industry, but it looks as if Sprint'sMarcelo Claure now wants a run at that title. In response to a snarky tweet by the T-Mobile CEO, Claure responded by saying that he was tired of Legere's "Uncarrier bullshit." He went on a four-tweet takedown of the company's policies, saying that it "trick[s] people," and that it's "all a fake show," before adding the hashtag #Tmobilelikehell. We're fairly sure that everyone who saw the exchange made the same ooo noise that pre-schoolers do when they know there's about to be a fight in the sandbox.

Add one more (potential) communications company deal to the pile: T-Mobile and Dish Network. According to the Wall Street Journal, the two are in "close agreement" about the structure of a combined company, with Dish CEO Charlie Ergen taking over as Chairman and T-Mobile leader John Legere serving as CEO for the two companies. Dish tried and failed to acquire Sprint a couple of years ago, while T-Mobile has made its own passes at joining with AT&T and Sprint. There's nothing final about the talks so maybe nothing will happen, but Verizon/AOL and AT&T/DirecTV could have company very soon.

T-Mobile's latest Un-carrier offering is going straight for Verizon's jugular. It's called the "Never Settle Trial," and as you might have guessed, it specifically mocks Big Red's #NeverSettle ad campaign. The trial, exclusively available to Verizon subscribers, will give you free access to a T-Mobile phone with an Un-carrier plan for two full weeks. You can even port your Verizon number without cutting your old line. If you decide to sign up for a Big Magenta Simple Choice plan by the end of the 14-day period, Legere and co. promise to shoulder any Early Termination Fee you incur worth up to $650. Actually, the company swears to pay for any service costs incurred due to the trial, even if you decide to stick with Verizon.

And the Un-carrier march continues unabated. This time, T-Mobile CEO John Legere address the consumer masses via YouTube to launch a new initiative that aims to help put a smartphone in the hands of anyone who wants one... and can pay their bills. Starting on January 25, T-Mobile's going to put less stock in your credit history and pay more attention to your payment history. If you've paid your dues on time over the past 12 months, you'll qualify for all those sweet, sweet no-money-down phone deals even if your FICO score looks a bit troubled. And new customers with less than sterling credit? They'll have to wait the 12 months before they get access to T-Mobile's carefully calculated largesse. Simple, no?

T-Mobile's latest Uncarrier announcement might lack the pomp and circumstance of a big media event, but CEO John Legere's conversation with Yahoo Tech's David Pogue is already proving fruitful. Once January rolls around, T-Mobile customers will be able to roll over their unused data into what T-Mobile calls a Data Stash for up to a year, and the carrier will give its subscribers "up to" 10GB of free data in their new stashes just to get things started. There's no cap on how big your stash can swell either, though T-Mobile's recent wideband LTE launches (in a nutshell: you get faster LTE without having to buy a new phone) might make it a little tougher to keep extra data around to bank.

It seems as though T-Mobile is speeding up on this whole UnCarrier thing. Speaking in San Francisco -- not in Vegas, where the other carriers are hanging out at CTIA -- CEO John Legere and Friends announced its latest move: Free WiFi calling and texting to all customers and corporate accounts. From here on out, every smartphone the carrier sells will come with the capability, and if you don't have one already, you're eligible to get one through T-Mobile's Jump early upgrade program. A nice benefit of this feature is a seamless transition from the network's Voice-over-LTE (VoLTE) coverage to your WiFi network.

Oh, you thought T-Mobile might take a breather from continually overhauling its wireless plans? Not so, dear readers. The magenta-hued carrier just announced a new $40 Simple Starter plan that grants you unlimited talk, text and 500MB of high-speed data... and it turns out that's just the beginning. T-Mobile CEO John Legere promised (in a feisty, pointed open letter to consumers) that the carrier has more to reveal over the next three days.

But let's not get ahead of ourselves here, as there are a few tidbits to keep in mind before jumping on this new deal. You won't get throttled when you bump up against that 500MB bandwidth cap, for one -- you'll instead be prompted to buy a day pass for more data access... or to sign up for one of the carrier's rejiggered Simple Choice plans instead. Perhaps that's not the more friction-free approach to getting your web surfing on, but it at least removes the possibility of getting smacked with overage fees. Would-be Simple Starter customers can still get T-Mobile to pay those termination fees if they're coming from another carrier, so those of you running on a budget may want to give this plan some thought.

Over the past year, T-Mobile's new policies have ushered in a new wave of changes to the way the US wireless industry works. It was the first national operator to introduce phone-financing plans, early upgrades and free international roaming; additionally, it also offers to pay your cancellation fee if you break another carrier's contract to move over. It appears that such practices must come at a cost: CEO John Legere announced that beginning April 1st, T-Mobile will no longer offer its Advantage Program, which features monthly employer rate plan discounts, to new customers. Existing beneficiaries will see the deduction removed from their accounts on April 25th. As a consolation, affected subscribers will now receive a $25 reward card every time they get a new phone.

Update (4/2): According to Legere and CMO Mike Sievert, T-Mobile has listened to its customers, and will let current users keep their discounts. More details are apparently coming tomorrow, but the new plan will only apply to new customers.

Update (4/3): The updated blog post is now available, and confirms that anyone in it, or who applied before April 1st will keep their discounts, however customers will need to verify their employment annually. Going forward however, the plan will work as described, with new customers under those plans getting a $25 reward card when they buy a phone.

Apparently AT&T isn't the only one thinking that T-Mobile's Uncarrier advertising campaign might be a touch too aggressive. The National Advertising Division, which is administered by the Council of Better Business Bureaus, has put out a statement scolding the magenta carrier for "flawed" advertising claims against its GSM rival. It takes particular issue with the assertion that T-Mobile offers 50 percent more bandwidth than AT&T because it only compares HSPA networks and doesn't take into account the latter's ever-increasing LTE grid. The NAD goes on to conclude that there's "insufficient evidence that AT&T's combined network, including LTE is more (sic) likely to be slowed by congestion than T-Mobile's," suggesting that T-Mobile halt all pronouncements otherwise. If it wishes to continue those claims, the NAD says it should outline the conditions where they would occur, such as the situations, locations or type of phones required to have an advantage.

Further, the NAD recommends that claims such as "most advanced technology" and "faster 4G service" should be discontinued or modified as well as the use of its 4G / 4G LTE coverage maps. It also said that T-Mobile's call quality claim was overly broad. T-Mobile has responded to NAD, stating that it believes it's already communicating its message well, but will take the suggestions into consideration. John Legere, T-Mobile's outspoken CEO, has already taken to Twitter in defense of the company's bold marketing approach. We've reached out to T-Mobile for a statement and will update this post when we get it.

Update: T-Mobile's Chief Marketing Officer, Mike Seivert has seen the NAD's recommendations for T-mo to make some minor modifications to its claims, and while they'll be taken under advisement, his company won't be changing its tune:

NAD's findings are a validation of our marketing approach. In fact, today's NAD findings won't result in any substantial changes to our marketing claims. We will continue to spread the word about our coast to coast 4G coverage, superfast 4G network, and superior call clarity, along with our message of simple, no annual service contract plans, unlimited data and the best upgrade program, JUMP!

It's no secret that T-Mobile feels very strongly about a specific shade of magenta. Long time readers will remember when Deutsche Telekom famouslycameafter your favorite tech site (spoiler alert: that would be Engadget) over the particular hue we'd chosen for our mobile section. T-Mo has evidently been jonesing for another chromatically inspired legal battle, as it just sued AT&T over the color of Aio Wireless' logo. While DT does technically have a German trademark on a single shade of magenta (RAL 4010), to anyone with eyes, it's evident that T-Mobile and Aio employ two completely different colors. Big Magenta's CEO John Legere weighed in on Twitter when he said, "Here is the Crayon box that @ATT must have been using :)," alongside a picture of RAL 4010-hued crayons (available at the source link below). Nobody wants to show up to prom in the same dress as someone else, but T-Mo appears to be grasping at straws. Magenta straws.

Right on the heels of its announcement of becoming the "UnCarrier", T-Mobile has dropped an early update on customer count for Q1. While its full earnings won't be announced until May 8th, it noted a net increase of 579,000 customers for the period, compared to a net loss of 349,000 in Q4 of 2012. It claims the increase was primarily due to continued focus on growing its MVNO customers base. Postpaid customer losses for Q1 are 199,000, far better than Q4's drop of 515,000, and 510,000 in the same period last year. President and CEO John Legere is certainly looking at the bright side (and keeping his language clean this time) claiming the data represents "positive momentum and the first positive branded growth in four years." We'll wait until the dollars and cents are counted -- and results from after its switch to no-contract plans and unsubsidized phone pricing are in -- before flying the magenta victory flag.

Back in the heat of summer, T-Mobile USA's then CEO Philipp Humm resigned to take up the mantle at Vodafone. In the interim, former COO Jim Alling stepped up to keep the chair warm while a permanent replacement was found. Today we learn that John Legere, former CEO of Global Crossing, will relieve Alling of those duties, and fill the top spot full-time. With 32 years experience in the industry, Legere also spent time at Dell as president of European, Middle East and African operations. For now, his first task will likely be leading the firm's LTE deployment, and trying to win some of the faithful back. Head past the break for the full PR and the new CEO's first video address to employees.
